Description

Diese Erfindung bezieht sich auf eine Signalleuchte der im Oberbegriff des Anspruchs 1 genannten Art.This invention relates to a signal lamp in the preamble of claim 1 Art.

Derartige Signalleuchten werden beispielsweise bei Eisenbahnen verwendet, um optisch den hinteren Teil von Zügen zu signalisieren, wobei diese Leuchten aus diesem Grund als "Zugende"-Signalleuchten bezeichnet werden. Ihre Betriebsweise ist intermittierend und sie erzeugen Lichtblitze, die das Vorhandensein eines voranfahrenden Zuges anzeigen. Obwohl im folgenden speziell auf derartige Zugende-Signalleuchten eingegangen wird, ist es verständlich daß die erfindungsgemäße Signalleuchte nicht auf diese Anwendung beschränkt ist.Such signal lights are used, for example, in railways to optically to signal the rear part of trains, these lights for this reason as "Zugende" signal lights are referred to. Their mode of operation is intermittent and they generate flashes of light that indicate the presence of a train in front. Although special reference is made to such train end signal lights in the following, is it is understandable that the signal light according to the invention is not for this application is limited.

Die Zugende-Signalleuchte ist ein unentbehrliches Sicherheitselement, das immer funktionieren muß; dies geht so weit, daß der Zug stehenbleiben muß, wenn eine Störung ihrer Signalfunktion auftritt.The pull end signal light is an indispensable safety element that always must work; this goes so far that the train must stop if there is a fault their signal function occurs.

Aus diesem Grund kann die Zugende-Signalleuchte nicht aus der eigenen elektrischen Versorgung oder von dem elektrischen Generator des Zuges selbst gespeist werden, sondern sie muß über eine autonome Speisequelle auf der Grundlage einer elektrischen Batterie verfügen.For this reason, the end-of-train signal light cannot come from its own electrical Supply or powered by the train's electrical generator itself, it must have an autonomous source based on an electrical one Battery.

Eine elektrische Batterie weist eine größere oder kleinere, jedoch begrenzte Kapazität auf, so daß das üblicherweise bei "Zugende"-Signalleuchten auftretende Problem darin besteht, die Entladung der elektrischen Batterie zu kontrollieren, um diese zu ersetzen, bevor die Signalleuchte aufhört, zu funktionieren, oder eine fehlerhafte Betriebsweise beginnt.An electric battery has a larger or smaller, but limited capacity, so the problem commonly encountered with "train end" signal lights is check the discharge of the electric battery to replace it before the Signal light stops working or a faulty mode of operation begins.

Ein bekanntes System besteht darin, immer eine Austauschbatterie zur Verfügung zu haben, um den Ersatz durchzuführen, wenn ein Leistungsanzeiger anzeigt, daß die im Gebrauch befindliche Batterie eine niedrige Ladung aufweist.A known system is always to have a replacement battery available have to perform the replacement when a performance indicator indicates that the in Battery in use has a low charge.

Dieses System ist für ein Sicherheitselement, das so wichtig ist, wie das vorliegende, wenig betriebsfähig, weil nur wenig Reaktionszeit bleibt und es unvorhersehbar ist, wann der Zeitpunkt des Ersatzes erreicht wird, der in der Mitte einer Strecke auftreten kann. Dies erfordert eine dauernde Aufmerksamkeit seitens verschiedener Personen, die abwechselnd Dienst haben, derart, daß jede geringe Unaufmerksamkeit zu schwerwiegenden Sicherheitsproblemen führen kann. Außerdem ergibt sich ein logistisches Problem dadurch, daß zu jedem Zeitpunkt und an jeder Stelle eine elektrische Reservebatterie verfügbar sein muß, damit diese zum Ersatz der nahezu leeren Batterie der "Zugende"- Signalleuchte verwendet werden kann.This system is for a security element that is as important as the present one, inoperable because there is little response time and it is unpredictable when the time of replacement is reached, which can occur in the middle of a route. This requires constant attention from different people take turns on duty, such that every little inattention too can cause serious security problems. There is also a logistical problem in that at any time and at any point an electrical Reserve battery must be available to replace the almost empty battery the "pull end" signal light can be used.

Ein weiteres bekanntes und weiterentwickeltes System besteht darin, eine alkalische primäre oder Haupt-Batterie mit großer Kapazität (Haltbarkeit über mehrere Betriebsmonate) und eine sekundäre oder Hilfs-Batterie in Not-Reservefunktion zu verwenden, die eine wesentlich kleinere Kapazität aufweist (Haltbarkeit über einige Betriebsstunden). Diese Haupt- und Hufs-Batterien werden in einer Pufferschaltung betrieben und sind mit einer Steuerelektronik verbunden, derart, daß eine Entladung der Haupt-Batterie automatisch die Hilfs-Batterie in Betrieb setzt und eine Leuchtanzeige aktiviert, die die Notwendigkeit des Austausches der Haupt-Batterie anzeigt und warnt, daß nur wenige Stunden für einen autonomen Betrieb der Hilfs-Batterie zur Verfügung stehen. Bei diesem System bedingt der Ersatz der Haupt-Batterie außerdem den Ersatz der Hilfs-Batterie, damit ein neuer Arbeitszyklus zur Verfügung steht, bei dem die ursprüngliche Not-Reservekapazität vollständig vorhanden ist, die sich aus dieser Hilfs-Batterie ergibt.Another known and developed system is an alkaline one primary or main battery with large capacity (durability over several Operating months) and a secondary or auxiliary battery in an emergency reserve function use that has a much smaller capacity (durability over some Operating hours). These main and hoof batteries are in a buffer circuit operated and are connected to control electronics, such that a discharge of the Main battery automatically puts the auxiliary battery into operation and an indicator light activated, which indicates the need to replace the main battery and warns that only a few hours are available for autonomous operation of the auxiliary battery. In this system, the replacement of the main battery also requires the replacement of the Auxiliary battery, so that a new work cycle is available, in which the original emergency reserve capacity is fully available resulting from this Auxiliary battery results.

Dieses System ermöglicht eine größere Reaktionsfähigkeit als das erstgenannte System, ist jedoch noch weit entfernt von der gewünschten Betriebsweise und ergibt logistische Probleme, die nicht vernachlässigbar sind.This system enables greater responsiveness than the first system mentioned is however still a long way from the desired mode of operation and results in logistical Problems that are not negligible.

Der Erfindung liegt die Aufgabe zugrunde, eine Signalleuchte der eingangs genannten Art zu schaffen, die eine höhere Betriebszuverlässigkeit und Wirtschaftlichkeit aufweist.The invention has for its object a signal light of the type mentioned to create, which has a higher operational reliability and economy.

Diese Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in claim 1.

Vorteihafte Ausgestaltungen und Weiterbildungen ergeben sich aus den Unteransprüchen.Advantageous refinements and developments result from the subclaims.

Die erfindungsgemäße Signalleuchte weist zwei elektrische Batterien, nämlich eine erste und eine zweite Batterie, auf, die beide untereinander gleich sind und die jeweils die erforderliche Kapazität für einen Betrieb über eine Norm-Betriebsperiode aufweisen. Diese ersten und zweiten elektrischen Batterien werden abwechselnd konstant und ohne Änderung bis zu ihrer Entladung elektrisch mit einer elektronischen Steuerschaltung über einen bistabilen Schalter verbunden. Die elektronische Steuerschaltung weist einen mit einer entsprechenden Signallampe verbundenen Ausgang und zwei weitere Ausgänge auf, die mit jeweiligen ersten und zweiten Leuchtanzeigen verbunden sind, die Leuchtdioden (LED) sind, die jeweils den ersten und zweiten elektrischen Batterien zugeordnet sind und die durch die elektronische Steuerschaltung bei der Feststellung der Entladung der elektrischen Energie der Batterien aktiviert werden.The signal light according to the invention has two electric batteries, namely a first one and a second battery, both of which are identical to one another, and which each have the have the required capacity for operation over a standard operating period. This first and second electric batteries are alternately constant and without Change until they discharge electrically using an electronic control circuit a bistable switch connected. The electronic control circuit has one a corresponding signal lamp connected output and two further outputs, which are connected to respective first and second light indicators, the light emitting diodes (LED), which are assigned to the first and second electric batteries, respectively by the electronic control circuit when determining the discharge of the electrical energy of the batteries are activated.

Die Betriebsweise dieser neuartigen Signalleuchte ist wie folgt: Wenn eine der elektrischen Batterien, beispielsweise die erste, entladen ist, bewirkt die elektronische Steuerschaltung, daß der bistabile Schalter die andere elektrische Batterie anschaltet, beispielsweise die zweite Batterie, wobei gleichzeitig die Leuchtdiode aktiviert wird, die der entladenen Batterie, in diesem Fall der ersten Batterie, entspricht. Dann verfügt man mit der zweiten elektrischen Batterie über eine weitere vollständige Norm-Betriebs periode, um den Ersatz der bereits entladenen ersten elektrischen Batterie durchzuführen. Weil ein bistabiler Schalter vorgesehen ist, d.h. ein Schalter, der in seinen beiden abwechseln- den Schaltstellungen stabil ist (für die erste elektrische Batterie oder für die zweite elektrische Batterie) folgt hieraus, daß während des Ersatzes der entladenen ersten Batterie durch Abschalten und Verbinden einer anderen neuen Batterie dieser bistabile Schalter in seiner Verbindungsstellung mit der zweiten Batterie bleibt, bis diese entladen ist. Zu diesem Zeitpunkt wird die ursprünglich zweite Batterie wie die erste Batterie behandelt, bis sie entladen ist, worauf der umgekehrte Vorgang wie bei dem vorhergehenden Vorgang durchgeführt wird, d.h. der bistabile Schalter gelangt in seine Verbindungsstellung mit der dann zweiten und vorher ersten Batterie, wobei gleichzeitig die zweite Leuchtdiode aktiviert wird, die anzeigt, daß die nunmehr erste und vorher zweite Batterie ersetzt werden muß. The operation of this new signal light is as follows: If one of the electrical Batteries, for example the first one, are discharged, the electronic control circuit causes that the bistable switch turns on the other electric battery, such as the second battery, the LED being activated at the same time that of the discharged Battery, in this case the first battery. Then you have the second electric battery over another full standard operating period to replace the already discharged first electric battery. Because a bistable Switch is provided, i.e. a switch that alternates in its two Switch positions is stable (for the first electric battery or for the second electric Battery) follows from this that during the replacement of the discharged first battery Turn off and connect another new battery to this bistable switch in its The connection position with the second battery remains until it is discharged. At this time the original second battery is treated like the first battery until it is discharged, whereupon the reverse process as in the previous process is carried out, i.e. the bistable switch comes into its connection position with the then second and previously first battery, the second light-emitting diode being activated at the same time , which indicates that the now first and previously second battery must be replaced.

Auf der Grundlage der Tatsache, daß jede der Batterien als solche in der Lage ist, einen Betrieb über mehrere Monate zu ermöglichen (Norm-Betriebsperiode) ergibt die neuartige Signalleuchte wichtige Vorteile, nämlich: Verfügbarkeit einer Not-Reserveperiode, die genauso groß ist, wie die Norm-Betriebsperiode, was zu einer starken Vergrößerung der Sicherheit führt und die Logistik enorm verbessert, und zwar aufgrund des großen Zeitbereichs, der für den Austausch der entladenen Batterie zur Verfügung steht, was zu einem Zeitpunkt und einer Stelle erfolgen kann, die am zweckmäßigsten ist; starke Vergrößerung der Betriebszuverlässigkeit der "Zugende"-Signalleuchte und dadurch, daß ein redundantes autonomes elektrisches Speisesystem über zwei gleiche und voneinander unabhängige elektrische Batterien zur Verfügung steht. Weil die "Zugende"-Signalleuchte ein grundlegendes Sicherheitselement, nicht nur für einen bestimmten Zug, sondern für den Schienenverkehr in seiner Gesamtheit darstellt, führt dies dazu, daß dieser Schienenverkehr Nutzen aus der großen Zuverlässigkeit und Sicherheit zieht, die sich durch die neuartige "Zugende"- Signalleuchte ergibt.Based on the fact that each of the batteries as such is capable of one Allowing operation over several months (standard operating period) results in the novel Signal light important advantages, namely: Availability of an emergency reserve period, the is the same size as the standard operating period, which leads to a large increase in the Security leads and the logistics improved enormously, because of the big one Time range that is available for replacing the discharged battery, what about a time and place that is most convenient; strong magnification the operational reliability of the "train end" signal lamp and in that a redundant autonomous electrical feed system via two identical and different independent electric batteries are available. Because the "pulling end" signal light a basic security element, not just for a particular train, but for represents rail transport in its entirety, this means that it Rail transport benefits from the great reliability and security that exists through the new "pull end" signal light.

Obwohl dies von geringerer Bedeutung ist, ist zu erwähnen, daß sich ein wirtschaftlicher Gewinn ergibt, der sich aus der Tatsache ergibt, daß mit dem neuartigen System die elektrischen Batterien bis zu ihrer vollständigen Entladung ausgenutzt werden können.Although this is of minor importance, it should be noted that it is an economic one Profits result from the fact that with the new system the electric batteries can be used until they are completely discharged.

    Gemäß der Erfindung besteht diese "Zugende"-Signalleuchte aus zwei elektrischen Batterien, nämlich einer ersten Batterie (1) und einer zweiten Batterie (2), die beide unter sich gleich sind und von denen jede die erforderliche Kapazität hat, um einen Betrieb über eine Norm-Betriebsperiode zu ermöglichen. Die erste Batterie (1) und die zweite Batterie (2) werden elektrisch in abwechselnder stabiler und nicht vor ihrer Entladung wechselnder Weise mit einer elektronischen Steuerschaltung (4) über einen bistabilen Schalter (3) verbunden, wobei diese elektronische Steuerschaltung (4) einen Ausgang, der mit einer entsprechenden Signallampe (5) verbunden ist, sowie zwei weitere Ausgänge aufweist, die mit jeweiligen ersten (6) und zweiten (7) Anzeigelampen verbunden sind, die Leuchtdioden (LED) sind, die jeweils der ersten (1) und zweiten (2) elektrischen Batterie zugeordnet sind und durch die elektronische Steuerschaltung (4) aktiviert werden, wenn die Erschöpfung der elektrischen Energie dieser Batterien festgestellt wird.According to the invention, this "pull end" signal light consists of two electrical Batteries, namely a first battery (1) and a second battery (2), both under are the same and each has the capacity to operate to enable over a standard operating period. The first battery (1) and the second Batteries (2) become electrically stable in alternation and not before they discharge alternately with an electronic control circuit (4) via a bistable Switch (3) connected, said electronic control circuit (4) having an output, which is connected to a corresponding signal lamp (5) and two more Has outputs with respective first (6) and second (7) indicator lamps are connected, which are light emitting diodes (LED), each of the first (1) and second (2) are assigned to the electric battery and by the electronic control circuit (4) be activated when the depletion of the electrical energy of these batteries is detected.

    Diese neuartige Vorrichtung ist schematisch in Figur 1 dargestellt, in der der bistabile Schalter (3) die erste elektrische Batterie (1) in Betrieb nimmt, damit die Signallampe (5) kontinuierlich Lichtblitze aussendet, während sich der (in dieser Figur nicht dargestellte, siehe Figur 2) Hauptschalter (8) in der Einschaltstellung befindet. Wenn die erste elektrische Batterie (1) entladen ist, stellt die elektronische Steuerschaltung (4) dies fest und bewirkt, daß der bistabile Schalter (3) auf die andere Anschlußstellung bewegt wird, in der die zweite elektrische Batterie (2) in Betrieb genommen wird, wobei gleichzeitig die erste Leuchtdiode (6) aktiviert wird, was den Fall der Entladung der ersten elektrischen Batterie (1) anzeigt. Man verfügt dann über eine weitere Norm-Betriebsperiode, die durch die zweite elektrische Batterie (2) geliefert wird, um den Ersatz der ersten elektrischen Batterie (1) durchzuführen, wobei während dieses Vorganges die zweite elektrische Batterie (2) angeschaltet bleibt, und zwar aufgrund des bistabilen Zustandes des bistabilen Schalters (3). Wenn die zweite elektrische Batterie (2) entladen ist, nimmt der bistabile Schalter (3) erneut die erste elektrische Batterie (1) in Betrieb (Zustand, wie er in Fig. 1 dargestellt ist) und es wird ein neuer Zyklus, gleich dem vorstehend beschriebenen, der Norm-Betriebsperioden eingeleitet.This novel device is shown schematically in Figure 1, in which the bistable Switch (3) puts the first electric battery (1) into operation so that the signal lamp (5) continuously emits flashes of light while the (not shown in this figure, see Figure 2) Main switch (8) is in the switch-on position. If the first electric battery (1) is discharged, the electronic control circuit (4) determines this and causes the bistable switch (3) to be moved to the other connection position, in which the second electric battery (2) is put into operation, with the first light emitting diode (6) is activated, which is the case of discharge of the first electrical Battery (1) displays.
